DataBinding

for data binding you only have to go to build.gradle module level file and add -----> buildFeatures {dataBinding = true}

ViewModel

    // ViewModel
    1. Go to plugins and add id 'kotlin-kapt'
    val lifecycle_version = "2.6.1"
    ViewModel
    implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version")

LiveData

    // LiveData
    implementation("androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version")
    Annotation processor
    kapt("androidx.lifecycle:lifecycle-compiler:$lifecycle_version")

ROOM Database

    // To use Room Database
     val room_version = "2.5.2"

    implementation("androidx.room:room-runtime:$room_version")
    annotationProcessor("androidx.room:room-compiler:$room_version")

    To use Kotlin annotation processing tool (kapt)
    kapt("androidx.room:room-compiler:$room_version")
  
    optional - Kotlin Extensions and Coroutines support for Room
    implementation("androidx.room:room-ktx:$room_version")

MVVM

Api

Retrofit

    // Retrofit
    implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'

Dependency Injection DI using Dagger-Hilt

    // Dagger-Hilt
    First, add the hilt-android-gradle-plugin plugin to your project's root build.gradle file:
    
    plugins {
          id("com.google.dagger.hilt.android") version "2.44" apply false
    }
    
    Then, apply the Gradle plugin and add these dependencies in your app/build.gradle file:
    plugins {
        kotlin("kapt")
        id("com.google.dagger.hilt.android")
    }

  dependencies {
      implementation("com.google.dagger:hilt-android:2.44")
      kapt("com.google.dagger:hilt-android-compiler:2.44")
  }

  Allow references to generated code
  kapt {
    correctErrorTypes = true
  }

  android {
  compileOptions {
      sourceCompatibility = JavaVersion.VERSION_1_8
      targetCompatibility = JavaVersion.VERSION_1_8
     }
 }

Firebase

Firestore + Storage + Authentication

    // Following includes all Dependencies for Firebase
    
    Firebase Authentication
    dependencies {
     Import the BoM for the Firebase platform
     implementation(platform("com.google.firebase:firebase-bom:32.1.1"))

     Add the dependency for the Firebase Authentication library
     When using the BoM, you don't specify versions in Firebase library dependencies
     implementation("com.google.firebase:firebase-auth-ktx")
    }

    Realtime Database
    dependencies {
     Import the BoM for the Firebase platform
     implementation(platform("com.google.firebase:firebase-bom:32.1.1"))

     Add the dependency for the Realtime Database library
     When using the BoM, you don't specify versions in Firebase library dependencies
     implementation("com.google.firebase:firebase-database-ktx")
    }

    Firestore Database
    dependencies {
     Import the BoM for the Firebase platform
     implementation(platform("com.google.firebase:firebase-bom:32.1.1"))

     Declare the dependency for the Cloud Firestore library
     When using the BoM, you don't specify versions in Firebase library dependencies
     implementation("com.google.firebase:firebase-firestore-ktx")
    }

    Storage
    dependencies {
     Import the BoM for the Firebase platform
     implementation(platform("com.google.firebase:firebase-bom:32.1.1"))

     Add the dependency for the Cloud Storage library
     When using the BoM, you don't specify versions in Firebase library dependencies
     implementation("com.google.firebase:firebase-storage-ktx")
    }

In future I will add JetPack Compose
